Amphitrite was the sea goddess wife of the sea god Poseidon
(aka Neptune). Amphitrite was either a Nereid and the daughter of Nereus and Doris, or an Oceanid and the daughter of Oceanus and Tethys. When Poseidon first sought Amphitrite as his bride, she was not interested: she fled to Atlas. But Delphin persuaded her to marry the sea god, for which service he was rewarded. Delphin's dolphin form was made into a constellation.
Amphitrite is associated with a golden spindle. To her husband Poseidon, she gave birth to Triton, Kymopoleia, Benthesikyme, and Rhode. Amphitrite was the mother of fish, shellfish, dolphins, and seals.
